Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

The only difference is the input parameters you get. Previously, before the AI versions were introduced, you had to always cast to pawn, get a controller out of it (or the other way around, not certain anymore), store both variables to operate on them.

With AI version, you just have it all right here. However keep in mind, that as far as I know, the AI version will only be called if the object using the Behavior Tree actually is an AI with a controller. You may use Behavior Trees for different things, most of which won't fire ExecuteAI - they will only fire regular execute.

Short story - ease of use only. All the events share the same story.

@vipeout thanks that was very a very useful explanation. For me it was great to understand that ExecuteAI required a Controller, since I have 1 PlayerController and many Characters that are not possessed, they are rather moved when told by other means (it's an RTS so you have many characters not tied to a specific controller)
